A heat wave is characterized by consecutive days of high temperatures (90s°F) combined with warm nights (60s-70s°F), creating dangerous conditions for those without air conditioning. High humidity makes heat feel more oppressive because it prevents sweat from evaporating, which is the body's primary cooling mechanism. When dew point and temperature are close together, the air becomes saturated with moisture, making it impossible for sweat to escape and causing a sticky, uncomfortable feeling. This combination of heat and humidity creates health risks and reduces outdoor comfort.

First Alert: Hot and humid days ahead, plus possibility of thunderstorms
Added:Local, this is a Fox 12 First Alert Weather Day.
>> All right, it is indeed a First Alert Weather Day. Let's take a look at some of our weather cameras here as you get started with Good Day Oregon Plus. That is a live look from our Newport camera.
>> Looks pretty good over there.
>> It does look pretty good over there.
Yeah, a little bit of fog rolling in, but I mean >> Yeah.
>> maybe rolling in, maybe >> Clearing out. It's more clearing up.
It's more clearing up. It's more dissipating or mixing out if you want to use a technical term.
>> Technical term.
>> We could do a whole First Alert Weather podcast about fog doesn't burn off.
>> Ah.
>> But we won't talk about that. That's >> Okay. That would be I I am down with that segment another time. We're taking a look there at Newport before the real heat comes in. There is our Ski Bowl camera looking at Mount Hood.
>> There's some smoke in that.
>> Is that mostly smoke that we're looking at? I know we're going to be getting into this here. Um, but yeah, so looking up there if you were heading to the mountain, that is what you were seeing on there. And let's go to uh one more here. We'll take a look at our Shriners camera.
And we've got >> now you can see that hazy sky off in the distance there as well.
>> The hazy sky right there for that. So, definitely some there. So, we're going to go ahead and bring this up. Hello everyone. This is Good Day Oregon Plus.
Thanks for joining us. I'm Greg Nibler here every weekday starting at 11:00 a.m. going all the way until our noon news. And we are joined by the one and only Carissa Sneek.
>> Yes, I'm here because it's First Alert Day.
>> First Alert Day. Yeah, meaning there is well, yeah, I think you've noticed if you've been outside at all in the last couple of days. I'll say I slept uh without some air conditioning in a very hot house the last couple of nights and not a lot of sleep.
>> So, you still don't have an air conditioner?
>> This is down uh down in the country at my parents' house.
>> Ah, okay.
>> So, the room I was in did not. And so, it's I can I can just say that it's been very, very hot.
>> Yes, and it's going to be more so today and tomorrow.
>> Well, let's get into this here. I'm going to go ahead and get over here and get us >> Yeah. Let's get up and look at some information. So, today >> go.
>> and tomorrow First Alert Weather Days for us for several reasons and we call this ones because one, the afternoons are going to be extremely warm, very hot. No, it's not uncommon for us to get into the 90s, but we have at least two days in a row in the 90s where the mornings will be in the 60s to low 70s.
And that's what Greg and I were just talking about, that inability to cool off at night for those of us that do not have air conditioners. This is when it starts getting into that dangerous. And then also, we do have some unhealthy air quality out there, which means opening up the windows even makes it harder because then you're starting to get some moderate quality here. If you're in Central Eastern Oregon, you're in really bad air quality. The good news is the next big change after this is a comfortable weekend ahead. Okay, let's talk about those details of your two first alert days, today and tomorrow.
So, Western valleys of Oregon and Southwest Washington, we're looking at maybe mid upper 90s, triple digits maybe for some of us. Very warm nights, mid 60s to low 70s in the urban areas. And then more humid than we typically see even in June.
>> Wow.
>> And looking at it being pretty sticky out there. I'll show you kind of where we're at and where we're going to be.
Let's look at the temperature trend or what is your temperature forecast. So, mid upper 90s, maybe triple digits today. You can see Thursday, Friday it drops back to just about average. And then we're actually looking at the weekend possibly having some cooler weather, getting into the maybe low 80s, maybe upper 70s on Saturday, but pretty much below average. The heat alerts that we have in place, one is for the greater metro area and Western Gorge, it's today and tomorrow. And then we did have an extreme heat advisory that was backed off to a heat advisory. So, two of them for the Eastern Gorge, Lower Columbia Basin. Again, both of those are today and tomorrow. The thunderstorm chance, this is where the reason and part of the reason we're seeing some muggy conditions is because that moisture that's coming in. So, it's more tomorrow afternoon into the evening and Thursday morning. We've looked at this map together a few times before, so wherever you see that red, that's that possibility. Now, today, no not all the ingredients that we need for those thunderstorms to produce today. Too >> Okay.
>> clear, too sunny, no moisture, everything's good. But >> looking at Wednesday.
>> This is looking at tomorrow right around noon, and you can see it's starting to build up, and especially there right along the Cascades. That's where you see that yellow. That's where the the west slopes, everything is building up. You get that lift, that instability that you need with uh we talked about the convective available potential energy.
You were talking to me about that before.
>> I was.
>> So, that's what we see for your afternoon. It stays with us all the way, and then it starts to back off a little and into Thursday morning, but then you'll notice eastern part of the region, central Oregon, kind of to the north, that potential would stay there if there's the other ingredient. So, here's the humidity forecast. Notice that this is midnight tonight when it starts backing off. So, what that means is going into this afternoon and into the evening, and that's when the humidity levels are going to rise. We call it the dew point forecast, where basically the amount of water that's in the air gets close to the temperature, and if you were to sweat, there's the inability for that sweat to escape to be, you know, evaporated off because the dew point and the temperature are so close.
>> Yeah.
>> And so, that's why you start feeling sticky because you can't release that moisture out of your body. The whole sweating process makes it impossible to feel better. We do drop back down tomorrow afternoon.
So, midday tomorrow, you'll feel normal again, and then it does pop back up as that chance for thunderstorms comes back in.
>> Okay. Just in time for the evening.
>> Just in time for the evening. Just when you want to open up your windows >> Right.
>> and cool off, but >> recommending should we not open up our windows at that time?
>> Well, here's the thing. On our side of the Cascades, on the west side, as you can see here, the air quality, we're in moderate. If you're sensitive, and I know there are many of us out there, they still even feel this, right? You you you walk outside, it might bother you. So, if you're somebody who's sensitive to uh any type of poor air quality then definitely would be harder to open up the windows. Look at though if you see around Bend just east and north of Bend they're in the very unhealthy range. So they're getting close to hazardous which is 500 AQI or higher. They're right in between that. They're getting into probably in the 3 400 range when you look at the AQI the air quality index.
>> Yeah.
>> So that's the worst. That's where the fires are.
>> I was going to say is that smoke coming from the fires that are right there?
>> There's some there's there's some in there and there's actually a little some to the north if you we've talked about the fire map this morning but yeah they're kind of the complex fires are in there. The ones that where you see the very unhealthy those are the areas that have the higher like go now evacuation orders going on. So not the best air quality and then of course as you can see and even if you look up just north of La Grande northwest of La Grande you can see it's also in the very unhealthy almost hazardous range actually.
>> Right. Those fires over there are pretty intense too.
>> Yeah. So so it's not the best and I can tell you from forecasting in Central Oregon for almost six years that this is just a really frustrating and difficult time because some people most people in Central Oregon have air conditioners because it gets you know pretty hot and dry.
>> Sure.
>> But you know you would just want to go outside. You don't want to be stuck in your house for the entire month of August or you know and then you have these fires and sometimes the smoke is from fires in the region sometimes it's being funneled in from other places and you just can't go out and enjoy what Central Oregon is all about because >> Right.
>> And one year my son and I were talking one year it was so bad it was actually the year of COVID. We couldn't even see our neighbor's house across the street.
It was so bad and so you couldn't go out you couldn't >> during the 2020 yeah 2020 fires yeah?
>> You couldn't get you know you couldn't go to somebody else's house cuz everything was being shut down you couldn't go you know outdoors or anything you couldn't go to a restaurant everything was so it was it's really >> It's not fun.
>> Not fun and not much of a relief. I mean you see at this point it's just it moves around. It doesn't really go anywhere.
It will back off a little overnight, but then it just starts filling back in as we get into, you know, the later parts of the day.
>> those fires are still going, so it's not like Yeah.
>> It's not It The only way it's going to go away is the fires are done or we have a nice healthy rain coming through that doesn't have any lightning and that's not going to happen. And so there's no relief other than those fires getting fought. Um the One of the good things is is we're not seeing because we're sitting under some high pressure, we're not actually seeing any major wind happening.
>> Okay.
>> So we're not looking at I'm going to show you this.
>> that's that's good. Out of all of this, you know, that's at least a good thing.
>> Yeah. So this right here where you see that hot, >> Mhm.
>> that's all just stationary. Like as you move >> it's so stagnant?
>> Mhm. Yeah. Kind of like a heat dome.
We're just it's not moving anything. We do Remember we talked about seeing some relief? So if I move the timeline here, it kind of slowly starts breaking down Thursday and then you see that low start to kind of push up right there.
>> Uh-huh.
>> So that will help us a bit, but again, the problem is it doesn't help the people that are to our south or southeast. It just pushes it over toward them.
>> Now does that wind coming in I mean I'm sure we'll probably get to that, but does that going to have an effect on those fires potentially?
>> It's not going Right now we're not seeing any major Yeah. That's not that we would be too worried about. So here's your air quality alerts uh that we have.
This is through Right now it's through tomorrow 4:00, but again, I These are one of those things that I'm like just expect this until the fires are out.
>> Yeah.
>> You know, like this was only supposed to be through noon yesterday and now it's through 4:00 tomorrow, but you saw the the smoke forecast map, no relief >> Yeah. Expect that it's just going to get updated and continued for >> Yeah. Yeah. And And this is all on the other side of the Cascades, but there is some upper air smoke, you know, like not the not the surface level smoke, but there is some that's actually drifting over toward us. It's not till we get a good onshore push that that would clear us out, but it doesn't make me feel good for the people that are off to our east because it becomes their problem.
>> I should >> say too also we are live on Facebook as well as you know all of our other platforms for if you are watching us live right now and I do have questions, uh feel free to drop those in. You may be watching this later this afternoon.
All relevant information just want to say it would be helpful.
>> Yep.
And then so then we have two things going on that I wanted to bring up for people that are you know being outdoors.
So the Portland Fire game is tomorrow.
Probably headed to the game at the hottest part of the day.
>> Yep.
>> know how how early people head out but if you're taking you know them try that those kind of things, you know things slow down, right? When tracks get hot and all that. So plan accordingly.
Expect that.
>> could be affected.
>> Mhm.
>> Yeah.
>> You're getting out there. Start of the game still in the low 90s, still hot.
That's at 7:00. Thankfully you'll be indoors.
>> Yeah, probably not a bad time to be indoors for >> Yeah.
>> an air conditioned building.
>> And then slightly cooler by the end of the game still mid 80s, you know, at 9:00. Games are a couple hours, 9:00 10:00 when you're heading home. Not going to be too bad. But the one that I was most concerned about was the one on Friday. But the good news is Oh.
>> What?
Somebody just moved our camera in there.
>> There we go. We're >> Or swipe >> must be in the other room.
>> Sure how that >> we're good. I think we're still okay.
>> Okay, we're still good. Okay. There we go.
>> So the start of the game uh that was a little jarring for us off >> Yeah, sorry.
>> So uh the start of the game for the match on Friday about 10° cooler than going out to the fire game. So that means that you will be good. You won't be having to worry about as hot.
Hopefully it won't be as smoky and definitely not as humid. We're not expecting it to be as humid during that time.
7-day forecast uh yesterday we went into the day the beginning of the day thinking we were going to hit 90 but it became evident as the morning went on that we were going to make it to the mid 80s. So 80 mid 80s, 86, 87. We did fine with that. Thursday likely not expecting so you know usually you consider a heat wave anything where you have 3 days at 90 or higher but we're still considering these two really hot days. We're still calling it a heat wave.
>> Okay.
>> Um for that, the hottest day likely will be tomorrow. You can see we kind of have the sun is a hazy sky. Thunderstorm chances Wednesday night into Thursday, and then Friday that Thorns game. From there on, it looks like, you know, potential of some morning clouds and then afternoons uh Saturday, Sunday, and Monday actually um 84 is where we get close to at the end of July uh for the average high end of July beginning of August. So, it'll actually drop back to slightly below and then back into the 50s and 60s. So, uh just a comfortable sun-cloud mix with some cooler starts in the morning. So, of course, during all of this, I am going to advise you to please download your the First Alert Weather app if you don't have it. We are keeping you updated on all things with smoke, with air quality, with heat advisories, with uh humidity levels, everything on this on our app. You can set the We call it a push alert, and it's just a 1-minute forecast where we give you the most important update, and you get it as it happens. So, you don't have to wonder or wait for your forecast to come up on the newscast or go search it online. It just gets sent right to your phone.
>> There you go. Yeah, good idea to grab that. I'll pull up our Steiner camera here one more time just to look here.
So, we're looking off the you know, towards the east here. Can't see Mount Hood at all in this shot. Usually you could.
>> Yeah.
>> So, is that all that smoke?
>> It's hazy, yeah. Smoky, yeah.
>> Okay.
>> Not not amazing air quality there, but that's all, you know, smoky hazy stuff mixed in with just very light cloud. And you can see if you look up to the right there, the higher that's cloud. So, it's kind of all >> Okay. Kind of mixing in together there.
>> Yeah, when you and when you So, when you get the smoke, basically, you know, when you're making clouds, or if you wanted to get into a conversation about cloud seeding, you have to have a condensation nuclei. And so, that's what the smoke is doing is it's giving something for whatever moisture is there to condense on.
>> Got you.
>> So, so smoke all work.
>> All all kind of run together.
>> little bit of both, probably. That smoke is having that dust, dirt particle, the smoke giving the cascades an ability to >> Uh, and we just have to see, yeah. Like you Like you mentioned, no real relief on those for a while.
>> And this was a concern we've had, I mean, we've been talking about it with the snow drought, with the >> We're talking about it since last winter or even before about what the potential was, yeah, for this summer, so Yeah, be careful out there. Have uh let's not start another fire on accident, which can happen.
>> It can. I think if I remember correctly, you know, some were started by like there was a car accident that started some and lightning strikes and things like that. So, just to not be something another factor. We already have enough happening.
>> Yeah, be careful on that.
>> please.
>> All right. Well, Katie, thank you for joining us. You know, this is why we get to do these, you know, it's great that we get to do these extended weather forecasts and looks at everything, kind of break it down a little bit for everybody. And as Katie mentioned, download that app, that way you have that on hand. You get any kind of updates that you need and uh it's just a great way to follow along, especially with everything going on out there.
>> Yeah.
>> The volatility of what, you know, could change. Yeah. Yeah, to be aware of it.
>> a lot we're watching for you right now and so we work hard to keep that app updated and get those out as much as possible and as quickly as possible. So, you know what to expect.
>> There we go. All right, thanks, Katie, and thanks everybody for joining us. So, we have more Good Day Oregon Plus. We're going to be here all the way until our noon news. We're going to take a quick break. We'll come back, we'll bring you up to speed on all these other stories we've been covering here throughout the day. If there's breaking news, we'll have that for you, too, but really there's a lot that's happened. And so, we want to going to make sure that you're aware of all that. So, we've got those uh coming up for you and a lot more, so stick right with us back here in just a couple of minutes with more Good Day Oregon Plus.
